Procedure
The product from Example 21d (0.67 g, 3.36 mmol) and the product from Example 9c (0.78 g, 3.36 mmol) in 10 mL ethanol were heated under reflux for 5.5 hr. The reaction mixture was cooled to room temperature and the solvent was removed concentrated under vacuum leaving yellow solid that was used without further purification (1.43 g, 100%).
